The film will be in theaters on October 7th.

“The Girl on the Train” follows Rachel Watson (Emily Blunt), a divorcee who obsessively views her former life from the window of a train. Every day, she takes the train in to work in New York City and it passes by her old house, where she lived with her ex-husband, Tom (Justin Theroux), who still lives there with his new wife, Anna (Rebecca Ferguson), and their infant child. While she tries to avoid the pain of her former life, she begins to obsessively watch an attractive couple — Megan (Haley Bennett) and Scott (Luke Evans) Hipwell — a few houses down. They seem perfect and beautiful to Rachel, but beneath the perfect surface lies trouble. One day, Rachel wakes up hungover with various bruises and no memory of the previous night’s events. Soon she learns that Megan has gone missing and Rachel becomes invested in the case to find out what happened to Megan but also if she was responsible. The film also stars Édgar Ramírez (“Zero Dark Thirty”), Allison Janney (“The West Wing”), Lisa Kudrow (“Friends”), and Laura Prepon (“Orange Is the New Black”). Watch a trailer for the film below.
